JAMES H. MURRAY, OF FAIRFIELD, MAINE.

FEED-WATER CONTROLLER OR REGULATOR.

Specification of Letters Patent.

Patented Feb. 4,1913.

Application filed November 27, 1911. Serial No. 662,716.

To all whom it may concern:

Be it known that I, JAMEs H. MURRAY, of Fairfield, in the county ofSomerset have invented certain new and useful Improvements in Feed-Water Controllers or Regulators; and I do hereby declare the followingto be a full, clear, and exact description of the invention, such aswill enable others skilled in the art to which it appertains to make anduse the same.

This invention relates to improvements in feed water controllers forsteam boilers,- the object of the invention being to provide simple andeiiicient means which will operate accurately and automatically tocontrol the supply of feed water to one or more boilers and maintain thelevel of the water in the boiler or boilers approximately uniform, andconstant.

With these and other objects in view the invention consists in certainnovel features of construction and combinations of parts as hereinafterset forth and pointed out in the claims.

In the accompanying drawings, Figure 1 is a view partly in section andpartly in elevation showing an embodiment of my invention. Fig. 2 is aplan view. Fig. 3 is a bottom plan view of the cover. Fig. 4 is asectional view illustrating the valve. Fig. 5 is a transverse sectionalview of the valve.

1 represents the body portion or cylinder of my improved controllerwhich may be provided in its bottom with an opening 2 normally closed bymeans of a base 8 on which the cylinder 1 is located and the lat ter isrigidly secured to said base by means of bolts 4. The lower portion orbottom of the cylinder is braced by means of triangular lugs 5 castintegral with the wall and bottom of the cylinder at the juncturethereof. The top 6 of the cylinder is similarly braced by means of lugs7 and the said top 6 is made with a large central opening 8 which isnormally closed by means of a cover 9 secured to the cylinder means ofbolts 10. The cover 9 is provided centrally with an annular flange 11surrounding an opening 12 and in order to strengthen said cover, radialribs 13 are provided. The base 14 of a valve casing 15 is secured bymeans of bolts upon the annular flange 11 of the cover 9,said valvecasing being thus so disposed as to communicate with the central opening12 in the top by cover. The valve casing 15 is provided at its upper endwith a removable cap or hood 16 whereby access may be had to the valvewithin said chamber for the purpose of making any adjustment of thevalve in case a different water level might be desired.

The cover 9 is provided with a series of depending arms 17 and the lowerends of these arms are rigid with a ring or collar 18 through which avalve rod 19 is guided. A float 20 is secured to the lower end of therod 19 and the upper end of said rod passes through and is secured to avalve 21 which is vertically movable within the valve casing 15. Thevalve 21 is made cylindrical in form and constructed with a series oflarge openings 22 formed by arms 23 connecting the lower portion of thevalve with the smaller upper portion 24 thereof, and to this upperportion 24, the valve rod 19 is secured by means of suitable nuts asclearly shown in Fig. 4. The valve casing 15 in which the valve isvertically movable, is provided interiorly with an annular duct 25communicating with a nipple 26 adapted for the reception of a pipeleading to the motor end of a pump,-said pump being suitably connectedto supply water to the boilers.

The cylinder 1 is provided at or near its upper end with a tap 27 forthe reception of a steam pipe leading from the steam dome of the boiler.The cylinder 1 is also provided with a tap or nipple 28 to receive 'apipe connected with the boiler or boilers approximately at the normalwater level so that the water level in the boilers and the water levelin the cylinder 1 will be always the same. The cylinder 1 may also beprovided near its bottom with a tap or nipple 29 for the reception of adrain pipe.

suitable gage may be provided and connected with the cylinder at thepoints 30-31 and a series of gage cocks may be provided at 32, 33 and34.

W ith the construction and arrangement of parts above described thewater level will be the same in the cylinder 1 as in the boiler orboilers and the steam pressure within the cylinder 1 will beapproximately the same as the steam pressure in the steam dome of theboiler and hence the valve connected with the float 20 will be balancedand its movements will be accurately controlled by the varying level ofthe water. When the water level descends, the float 20 will also descendand cause suflicient downward movement of the valve 21 to move theopening 23 thereof into alinement' with'the annular duct 25 in the valvecasing,thus permitting steam to pass from the interior of the cylinder lupwardly through the cylindrical valve 21 and escape from the latter andfrom the duct 25 to the steam pipe connected with the nipple 26, saidsteam pipe conducting the steam to the motor end of a pump, aspreviously explained. It will be observed that as the steam whichsupplies the pump first enters the cylinder 1 before reaching the valve,any condensation which might occur will take place within said cylinderrather than in the valve or valve casing.

Various slight changes might be made in the details of construction ofmy invention without departing from the spirit thereof or limiting itsscope and hence I do notwish to restrict myself to the precise detailsherein set forth.

Having fully described my invention, what I claim as new and desire tosecure by Letters-Patent, is,

1. In a feed water controller, the combination of a. cylinder havingsteam and water connections, a cover on said cylinder, said cover havingan opening communicating with the cylinder and surrounded by a seat, avalve casing secured on said seat and having a steam outlet, a valvemovable in said casing and comprising a tubular lower portion closelyfitting said valve casing, and an upper portion consisting of aplurality of arms and a collar at the upper ends of said arms, a floatin the cylinder, a rod connected with the float and adjustable devicesconnecting said. rod with the collar at the upper end of the valve.

2. In a feed water controller, the combination with a cylinder providedwith steam and water connections, of a cover on said cylinder having anopening surrounded by a seat, said cover also having integral dependingarms supporting an integral collar in line with the opening in saidcover, a valve casing mounted on the seat on the cover and having asteam outlet, a valve in said casing, said valve having a cylindricallower portion closely fitting said casing and having an upper portioncomprising a plurality of spaced arms and a collar at the upper end ofthe latter, a float in the cylinder, and a rod secured to said float,passing up through the first mentioned collar and secured at its upperend to the collar at the upper ends of the arms of the valve.

' 3. In a feed water controller, the combination with a cylinderprovided with steam and water connections, and a cover onsaid cylinderhaving a central opening surrounded by a seat, of a valve casing mountedon said seat and having a steam outlet and an annular duct communicatingtherewith, a valve in said'casing, said valve comprising a lowercylindrical part closely fitting within said casing to open and closesaid steam duct, and an upper part consisting of a collar and aplurality of spaced arms connecting said collar with the cylindricallower portion of the valve, a float in the cylinder, a rod secured atits lower end to said float, and means adjustably connecting the upperend of said rod with the collar at the upper end of the valve.

4. In a feed water controller, the combination with a cylinder providedat its respective ends with braced heads having openings, and alsoprovided with steam and water connections, and covers removably securedto said heads respectively, of a valve casing having a steam outlet,mounted on one of said heads, said valve casing provided with aremovable cap, a valve having a lower cylindrical portion closelyfitting said casing and having lateral openings above said cylindricalportion, a float in said cylinder, a rod secured at one end to saidfloat, and

means connecting the upper portion of said rod with the upper end ofsaid valve.

In testimony whereof, I have signed this specification in the presenceof two subscribing witnesses.
